Picked this one up from Warp2Search.net. For those of you using the Detonator 40.52's, this is the file to get!

Ok this is for all the peeps that emailed me asking how do I enable the overclocking utility in NVIDIA Detonators 40.52 and how do I enable the Direct3d setting!

And before I forget the refresh rates tab's do work! if it's greyed out? click on the override refresh rates , then choose the resolution you want! double click that and it should open a tab with all the available refresh rates mine goes upto 120hz then press apply then ok! but remember if you try and set it back to applications control refresh rates! it will set them back to your default setting tested on Widows 98SE
